Fabricated precast concrete pavement slab assembly, pavement structure and construction method of pavement structure

Abstract

The invention provides a fabricated precast concrete pavement slab assembly, a pavement structure and a construction method of the pavement structure. The pavement slab assembly comprises a precast concrete pavement slab A and a precast concrete pavement slab B, grooves and pre-buried bolts are arranged on the side faces of the adjacent pavement slabs, connection is achieved through the fastening nuts, construction is fast, tight attachment between the pavement slabs and the base layer is achieved by grouting the bottoms of the pavement slabs, the connection requirement of the joints is met by grouting the joints between the pavement slabs, therefore, the structural performance of the precast concrete pavement structure in all directions is ensured. Thus, the technical problems that in the prior art, the inter-plate connecting process of the fabricated precast concrete pavement plate is complex and poor in effect, and the fabricated precast concrete pavement plate and the base layer cannot be tightly attached are solved, large-area and multi-section simultaneous construction can be achieved, meanwhile, the requirement for the flatness of the base layer is further lowered, and the construction quality and the construction efficiency are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of assembled prefabricated concrete pavement, and in particular relates to an assembled prefabricated concrete pavement assembly, a pavement structure and a construction method thereof. Background technique [0002] At present, concrete pavement projects such as municipalities, bridges, and airport roads in my country mainly adopt the method of cast-in-place construction. This type of method has problems such as difficult concrete maintenance, many cracks, and poor durability. Especially for airport road projects, the impact on concrete cracks The requirements are very high, and repair problems often occur during construction, and the actual service life often fails to meet the design requirements. [0003] With the development of my country's prefabricated concrete structures, the production of precast concrete components has become very mature, and the materials and techniques for connecting nodes between c...
